  1. Mean ± standard deviation
  2. Statistical evaluation was performed on measurements from individual fish in order analyse whether stunning success in individual fish had an impact on clinical chemical parameters of the blood
  3. a measurements of this parameter are not significantly different between farms
  4. b measurements of this parameter are significantly different between farms
  5. c Data distributed normally, statistical evaluation by ANOVA followed by Tukey’s post hoc test. Other parameter: Data distributed not normally, statistical evaluation by ANOVA on ranks followed by Dunn’s post hoc test. Data for a clinical chemical parameter sharing the same superscript letter are not significantly different (total n = 113)
